Each year, the Nobel Peace Prize laureate is celebrated with a concert in Oslo, Norway, the day after he/she is honored at the awards ceremony. Since 2000, the Nobel Peace Prize committee has triumphed in tapping top-notch musical talent—no disrespect to Boyz II Men, who serenaded Jody Williams, a political activist honored in 1994 for her work banning and clearing land mines—and in pulling A-list hosts willing to make the trip to Norway. For instance: Liam Neeson and Meryl Streep hosted in 2001, Oprah Winfrey and Tom Cruise (!) hosted in 2004, Sharon Stone and Anjelica Huston hosted in 2006, and Scarlett Johansson and Michael Caine hosted in 2008. Today, it was announced that Sarah Jessica Parker will co-host this year’s concert honoring the European Union, alongside an actor whose critical breakthrough involved a mask and who has co-starred in lovably hokey rom-coms involving Katherine Heigl and Jennifer Aniston. Can you guess this year’s Nobel Peace Prize Concert co-host?

The unlikely rom-com actor is Gerard Butler, who in all fairness, also led 300 Spartans into battle in Zack Snyder’s stylish action film 300. Scheduled for December 11, the concert will include performances by Jennifer Hudson, Seal, Norwegian hip-hop duo Karpe Diem, and Swedish singer Laleh. According to Billetservice, the Norwegian Ticketmaster, tickets run between 635 and 1045 Norwegian krone, approximately $110–$180. It is also worth noting that, perhaps in an attempt to deter co-hosts from backing out of their duties at the last minute, the Wikipedia page for the Nobel Peace Prize Concert has cattily recorded all of the co-hosts who have cancelled on short notice. This list includes Meryl Streep in 2000—she was replaced by Jane Seymour and co-hosted the following year—and Tommy Lee Jones, who had agreed to celebrate the 2007 laureate and his former Yale classmate, Al Gore. (At the last minute, Kevin Spacey was recruited as a replacement—he’s good at that—and co-hosted with Uma Thurman. So if you are ever asked what Meryl Streep and Tommy Lee Jones have in common, aside from their roles in Hope Springs, you will be prepared!
